TURN AND INSEAM SHOE SEWING MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed August 26, 1919. Serial No. 319,999.

To all 10 7mm it may concern:

Be it known that I, RALPH SGARCELLO, a citizen of the United States, residing at Los Angeles, in the county of Los Anigeles and State of California, have invented new and useful Improvements in Turn and Inseam Shoe Sewing Machine Attachments, of which the following is a specification.

My object is to make a turn and inseam shoe sewing machine attachment, and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is a fragmentary perspective of the sewing machine provided with a turn and inseam shoe sewing machine attachment embodying the principles of my invention.

Fig. 2 is a cross section through the attachment at the plane of the needle and showing the operation.

Fig. 3 is a perspective of the stripper plate and mounting.

Fig. 4 is a perspective of the needle plate and mounting.

Fig. 5 is a cross section similar to Fig. 2 and showing a modification and its operation.

The stripper plate 1 is curved in cross section or end elevation and has a needle slot 2.

The mounting for the stripper plate 1 comprises an arm 3 extending from one side of the plate, a base 4: at the lower end of the arm 3, a pintle 5 extending from the base i, a socket 6 in which the pintle 5 is rotatably mounted, the set screws 7 tapped through the socket 6 to engage the pintle 5, and the base 8 extending from the lower end of the socket 6.

The base 8 fits upon an abutment 9 forming a part of the sewing machine frame and is held in place by a cap screw 10. The needle plate and mounting comprise a block 11 having screw holes 12 and 13, a neck l l extending from the block 11, and a head 15 extending from the neck 14: and having a needle slot 16 in one side. The block 11 is secured to an abutment 11' by bolts inserted through the holes 12 and 13.

This device is especially adapted for turn and inseam work.

The shoe sole 17 has inclined cuts 18 to form flaps 19, and the shoe upper 20 is brought around the edge of the shoe sole 1? agalnst the outer faces of the flaps 19 and the sole and upper are placed in position with the head 15 in a cut 18 so as to turn the flap 19 outwardly into a substan tially horizontal position while the bodyof the sole 1'? is in a vertical position.

The stripper plate 1 passes above the upper 20 and the needle 21 and awl 22 pass back and forth through the slot 16 to sew the upper to the flap. After the seam has been extended the desired distance the upper and sole are turned inside out and the shoe finished.

In the modification shown in Fig. 5, the stripper plate 23 is flat so that a sole 24, an upper 25 and a welt 26 may be sewn together, and in this operation the head 15 passes inside of the flap 27 and the welt 26 presses against the lower side of the stripper plate 23.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. A turn and inseam sewing machine attachment including an arm, a stripper plate on said arm, a pintle on said arm, a socket to receive said pintle, a set screw for holding said pintle in said socket, and a head mounted so that it will pass in an inseam cut in a shoe sole and press the flap outi\yardly so that an upper may be sewn to the 2. In a turn and inseam shoe sewing ma chine attachment the combination of a stripper plate, means for mounting the stripper plate, a needle plate mounted below the stripper plate, said needle plate comprising a head having an open needle slot at its rear forming a hook-like structure and adapted to pass in an inseam cut and support the parts to be sewn in a substantially horizontal position.

In testimony whereof I have signed my name to this specification.

RALPH SGARGELLO.
